Job Description

Are you a Senior Backend Engineer looking for an opportunity where your work has tangible environmental impact, and you’re trusted to shape and scale real-world systems from the ground up?

Techmunity are hiring a Senior Backend Engineer for a Series A ClimateTech start-up who’re working with some of the biggest banks and transport brands in the world.

They’ve built a powerful platform helping accelerate the transition to zero-emission mobility, and recently signed a global financial player as they expand across the US and Middle East.

You’ll join a lean, high-performing team and take ownership of a core backend – the work here isn’t a refactor-heavy role – the backend is solid, but evolving fast.

They need someone who can understand a large codebase, pick up new features quickly, and help the team scale reliably.

You’ll need:

  • 5+ years of backend development experience (ideally already operating at senior/lead level)
  • Strong experience with C# and cloud (Azure preferred, AWS welcome)
  • Familiarity with CosmosDB or similar NoSQL databases
  • Experience working in financial services or other regulated/data-heavy domains
  • TDD mindset, comfort in large codebases, and an interest in DevOps (GitHub Actions, CI/CD pipelines, etc.)
  • Curiosity around AI tools (e.g. GitHub Copilot, CodeRabbit – training is provided!)

For this Senior Backend Engineer role they are paying between £80,000 to £110,000 depending on level of experience, plus shares, private medical healthcare, life insurance and more.

The team come in to work 3 days per week (Monday, Tuesday and Thursday) – so are looking for someone who enjoys some face-to-face collaboration.
